` To all whom 'it may concern:

Be itknown that I, 'JULIAN R. riquair, a citizen ofthe United States,'and a resident of Bristol, in the county of Hartford and State of Connecticut, have invented a new `and Improved Percolator, of which the-fol-V lowing is a specication.

Thisv invention relates to the general class of devices for making hot beverages, such as' coee or. the like, and the object of the invention 1s to provide a device of this class having novel features of advantage and mint.

A form of device inthe useof which the objects sought may be attained is illustrated.

in the accompanying drawings, in which-'- Figure l is a view partially in elevation of a coffee pot or peicolator embodying my invention. Fig. 2'is a perspective view of the fountain base and tube. lFig. 3 is alde-V tail View jin central lengthwise' section through the bottom 'portion of a pot and fountain base, illustrating another embodiment of the invention.

The device embodying the invention herein shown and ,described has a heating or generating chamber arranged to contain the liquid .inv a comparatively thin mass, which isof particular advantage in that the liquid may be quickly heated to a temperature to cause flow through the fountain tube, the means for supplyin the 4liquid 'to this generating -chamber eing such as not to reduce the temperature of the liquid therein to an extent to unduly check the fiow through the fountain tube.

Inv the accompanying drawings the nu- `meral 5, indicates a pot as a whole, which may be of any desired form and constructed of any suitable material, this pot having a spout G and a handle 7. rllhe pot incluses and constitutes a reservoir 8 to contain thev main body of the liquid contents, andthe bottom of the pot has a depression 9 preferably located in the centerV thereof.A A fountain base 10 is 'constructed to set inthe depression '9, thisbase having a vclosed vinsulating chamber 11, the air in which acts r as` an insulatory to check thet-ransmissionof y L.heat` from the heating'or generating chani f ber to, the main "contentsof the pot in the i reservoiry 8. The bottom of the fountain 4 f l baseis'concaved as shown in Eig. v1 of 'the' drawings to pi'ovidea recess or generating i chamber 12, the edge of which is llocated near the bottom 14 of the depression 9. An

apron 1 5 extends around the fountain base, pro]ecting downward and resting upon the bottom 16 of the main body of the pot and near the edge of the depression 9, thus providing an inletchamber 17 betweenthe wall of the depression and the Vfountain base, which chamber communicates through the passage underneath the edgel with the generating chamber formed by the recess 12. OpeningslS arey formed through `the apron lifor the supply of liquid from the reservoir 8 to the inlet chamber and thence to the heating, or generating chamber 12. A fountain tube 19- secured to the fountain base 10 extends throughl the insulatingy chamber l1 and reservoir 8, the opening through this tube communicating with the generatingchamber or .recess l2. Anninsulating tube 20 extends along and surrounds the fountainatube 1,9, providing an insulating chamber 21` between the` fountain tube and 4the insulating tube to prevent the cooler content of the reservoir 8 from lowering the temperature of the liquid, passing through the fountain tube and thus checking the liow through such tube.

A receptacle 22 for coifeevor like material is constructed to fit and rest within an opening 23 at'thetopof the pot,the bottom 24 of the receptacle being perforatedin a inan'- i ner common to devices of thisclass. A. sleeve 25 projects upward within the recep tacle from the perforated bottom,- the upper endof the sleeve beingA providedv with means for permitting overflow of liquid from the receptacle.` The preferred form .of overflow,

as shown herein, consists ,of perfor-ations 26 in the sleeve near the upper end. The perfoi-ations 26 are formed in a rounded end 27 l*of the sleeve which is reduced as shown and within the otherwise open end of zthe recepv tacle 22, thisV basin having av perforated bottoni 31 and aucover 32. ,The outlet end of the fountain tube 19 is locate'd in this basin and the cover 3Q is preferably composed of glass. Any suitable means for securing the receptacle 22 to the pot and the cover to the basin may be employed.

lVhen the device is used in a potwithout the depression hereinabove described, the partsare constructed and arranged as shown in'Fig. 3 of the drawings in which 'the pot B3, the lower portion'only of 'which is shown,

has alflat bottom 34 upon which the apron, i 15 rests.

lThe fountain base 36 is of similar constructionjto that hereinabove described, having a fountainctube 37 projecting upward therefrom and aninsulating tube 38 surrounding the fountain tube. In this form of construction the-apron 15 is preferably of a lengt-h to raise the edge 39 of the fountain base slightly from the bottom of the pot to allow entrance of fluid to the chamber underneath vthe fountain base.

Any means for 'permitting entry of fluid into the chamber between the apron .15 andthe fountain base may be employed, such as seri-ations 40 or openings as described with reference to the apron 15, and, in fact, withont such openings or serrations it will be found tlia-t the pressure of the main body of the liquidy within the'pot will cause a flow under the edges of the apron and fountain vbase sufficient to keep the chamber underneath said base properly supplied with fluid, and I' do not therefore limit .myself to a structure in ivhichtliev openings or serra'tions are present in the apron or in which a decided space is provided between the edge of the fountain base and the bottoni of the pot,

as the unevenness of the contacting surfaces or the ability of the fountain base to move upward to a slight degree, `either or both,`

will allow for entry of 'fluid to t-he chamber underneath the fountain base for the pur# -in the main body of the pot.

pose described. y

T he construction oftheapron and thenction of the fluid are such that the air cannot be entirely displaced from the'chamber between theapron andthe -fountain base, a space being thus left'at the top-of the chamber between such parts, this being denoted by the numeral ll in Fig. l and by the numeral 42 in lFig. 3 ot the drawings. This provides an insulating space or chamber to aid in preventing the raising of the tempera-` ture of the fluid and contents of the main portion of the pot under the influence of the hotter liquid in the chamber underneath the fountain tube,` or the, lowering of the latter under the influence of the cooler contents The insulating chamber within the fountain base may communicate with the/chamber between the fountain and insulating tubes, as shown in Fig. ,3 of the drawings. or be separated 'therefrom as .shown iii Fig. l.

ltwill be noted that the improved device "tents of the receptacle,

herein lillustrated and described lnot only provides'for the immediate heating of the contents of the generating chamber, thus providing a quick and rapid flow through the fountain tube, but the construction of 70 thebas'in providesl means for diffusing the liquid contents over the entire surface of the coffee or other material contained in the receptacle 22, and should the flow of liquid through thefountain tube be faster th-an the.

percolation ofthe liquid. through the consiich excess flow is taken care of by the overflow through the sleeve The construction off'the overflow from the 80 receptacle 22 is not confined to a `perforated sleevey as shown herein, as various meansvof effecting this resultymaybe .devised lwithin the scope and intent of the invention,l and while there is shownand described vhereinf a preferred form of construction embodying the invention as la whole, such'coiistruction may be departed from to a greater or lesser extent without avoiding the invention, which is therefore not limited to the precise vcon- 90 struction herein shown aiid described...
